abstract = {Power converters are the basic elements of any power electronics system in many areas and
applications. Among them, the push–pull converter topology is one of the most widespread due to its
high efficiency, versatility, galvanic isolation, reduced number of switching devices and the possibility
of implementing high conversion ratios with respect to non-isolated topologies. Optimal design and
control requires very accurate models that consider all the non-idealities associated with the actual
converter. However, this leads to the use of high-order models, which are impractical for the design
of model-based controllers in real-time applications. To obtain a trade-off model that combines the
criteria of simplicity and accuracy, it is appropriate to assess whether it is necessary to consider all
non-idealities to accurately model the dynamic response of the converter. For this purpose, this paper
proposes a methodology based on a sensitivity analysis that allows quantifying the impact of each
non-ideality on the converter behaviour response as a function of the converter topology, power and
frequency. As a result of the study, practical models that combine the trade-off between precision and
simplicity are obtained. The behaviour of the simplified models for each topology was evaluated
and validated by simulation against the most complete and accurate non-ideal model found in the
literature. The results have been excellent, with an error rate of less than 5% in all cases},
